The utility model relates to a high -voltage electroscope technical field, concretely relates to safe electroscope, include infrared lamp, bee calling organ, automated inspection button, shell, insulator spindle, probe, handhold portion and turn to the part, the utility model discloses a turn to the part, can rotate a plurality of angles in the operation, it is with simple theory of mechanics, the protruding setting in the draw -in groove, as turning to partial nimble fixed portion, do not drop out can not follow the draw -in groove again when can rotating wantonly in, bracing piece and spacing draw -in groove can be fixed the rotatory angle of arch, make and to stabilize in the use angle, but the fixing clip is dead again in nimble changeable while of angle, very big having made things convenient for in daily detection, because of the inconvenient difficulty of bringing of angle, insulator spindle and handhold portion have on originally insulating basis and have added one deck high voltage?insulation coating, feasible measurement is safer, the utility model discloses simple structure, the security performance is higher, and a lot of angle?measure has very strong practicality.
